Pretreatment Factors Associated with the Outcome of Stuttering Therapy

Abstract

Measures of stuttering behavior, personality, and attitudes about speaking were obtained from 20 stutterers at the beginning of treatment. These measures were correlated with three measures of stuttering behavior a year after treatment. Pretreatment attitudes were most highly related to outcome. followed by pretreatment stuttering behavior, and then personality measures. Multiple regression analyses of the pretreatment measures demonstrated that combinations of these variables correlated moderately high (r = 0.79, 0.66, 0.73) with outcome. Prediction equations derived from the multiple regression analyses were used to predict outcomes for an independent group of 18 stutterers. Predicted and actual outcomes were shown to be correlated moderately high (r = 0.75, 0.73, 0.51). Suggestions for clinical use of predictive factors are given. Implications for the design of treatment and understanding the nature of stuttering are discussed.
